Add DT_HASH to native library for Android 5.x compatibility

[Copilot]

Android 5.1 devices fail to launch the app because librime_jni.so is built with GNU hash only, which older Android dynamic linkers cannot load. The Java crash during MainActivity startup is a downstream effect of System.loadLibrary("rime_jni") failing in native library loading.

• Root cause

  • librime_jni.so was linked with --hash-style=gnu
  • Android 5.x expects the legacy SysV DT_HASH section; with only DT_GNU_HASH, dlopen() fails with empty/missing DT_HASH

• Change

  • Update the native linker flags in app/src/main/jni/CMakeLists.txt
  • Switch from GNU-only hash output to dual hash output so the shared library contains both DT_HASH and DT_GNU_HASH

• Effect

  • Restores compatibility with Android 5.x loaders
  • Preserves behavior on newer Android versions
